Definitions

  • the present invention relates to a method of preparing a lithium metal anode, and more specifically, to a method of preparing a lithium metal anode with high energy density.
  • lithium ion secondary batteries may utilize a transition metal oxide (such as LiCo O 2 ) as a cathode active material and carbon as an anode active material. Carbon has a theoretical capacity of 372 mA/g, resulting in a battery with low energy density.
  • a transition metal oxide such as LiCo O 2
  • carbon has a theoretical capacity of 372 mA/g, resulting in a battery with low energy density.
  • lithium metal As an anode instead of carbon, a battery has higher energy density and lower weight since lithium has the highest potential difference ( ⁇ 3.045 V vs a standard hydrogen electrode (SHE)) among metals and a low density (0.53 g/cm 2 ), to go along with its high theoretical capacity of 3860 mAh/g.
  • SHE standard hydrogen electrode
  • lithium metal tends to react with oxygen, nitrogen, and carbon dioxide when exposed to air, even at room temperature, thereby forming Li 2 CO 3 , Li 2 O, LiOH and other like substances on its surface. Thus, it is very difficult to obtain lithium metal with a clean surface.
  • lithium metal tends to react with an electrolytic solution to form a passivity layer, which is not chemically or physically uniform, thereby causing a localized current density on an electrode surface. This facilitates localized dendrite growth, resulting in a short circuit in the battery. Moreover, the formation of dead lithium on the anode reduces its capacity. Accordingly, an organic, inorganic or organic/inorganic hybrid thin film may be formed on the lithium metal surface to inhibit a reaction between the lithium metal and the electrolytic solution. However, if the lithium metal surface to be coated is not initially clean, the thin film does not function well as a protective layer.
  • the substrate may be composed of a metal, including copper, aluminium or nickel, or a film of polymer, including polyester, polyethylene, polypropylene or polyimide.
  • depositing the lithium metal generates a lot of heat, which will likely deform a thin substrate.
  • a 15 ⁇ m thick substrate may result in a battery with low energy density.
  • U.S. Pat. No. 6,214,061 discloses a method of preparing an electrode in which a 50 ⁇ copper film is formed as a release layer on a substrate composed of polymer. An inorganic film, a lithium film and a current collector are sequentially formed on the release layer, and the polymer substrate is then released.
  • a release component of copper film has poor release properties, and after the substrate is released, copper may remain on the protective inorganic layer, thus inhibiting lithium ion movement and deteriorating the battery's performance.
  • the present invention provides a method of preparing a lithium metal anode with high energy density per volume.
  • the present invention also provides a lithium metal anode with high energy density per volume.
  • the present invention discloses a method of preparing a lithium metal anodeincluding forming a current collector on a substrate that includes a release component, depositing a lithium metal on the current collector, and releasing the current collector with the deposited lithium metal from the substrate.
  • the present invention also discloses a lithium metal anode comprised of a current collector layer and a lithium metal layer formed on the current collector layer.
  • the current collector layer and the lithium metal layer were released from a substrate that included a release layer.
  • FIG. 1 is a cross-sectional view of a lithium metal anode after a separator is attached and before being released from a substrate.
  • FIG. 2 shows a photograph of a lithium metal anode prepared according to an exemplary embodiment of the present invention.
  • a current collector is formed on a substrate that includes a release component.
  • the thickness of the substrate on which the lithium metal is deposited may be increased to prevent heat deformation of the substrate when depositing the lithium metal.
  • the substrate is released from the current collector, resulting in a thin lithium metal anode. Accordingly, the energy density of the battery may be increased.
  • a current collector is formed on a substrate that includes a release component, a lithium metal is deposited on the current collector, and the current collector with the deposited lithium metal is released from the substrate.
  • the lithium metal may be pretreated or a protective layer may be deposited on it. Pretreating is performed with oxygen plasma, nitrogen plasma, carbon dioxide plasma, by a simple exposure to gas, by depositing an inorganic material having an ionic conductivity, by depositing a copper metal film or by depositing a nickel metal film.
  • the lithium metal may react with a solvent of the solution, which may damage the lithium metal surface.
  • Pretreatment reduces the lithium metal's reactivity and prevents surface damage.
  • pretreatment by nitrogen plasma may form a lithium nitrides layer on the lithium metal surface.
  • pretreatment by deposition of a copper film copper diffuses toward lithium when the battery is operated, and thus there is no problem in the movement of lithium ions.
  • a protective layer may be formed on the lithium metal surface.
  • the protective layer may be a metal layer, an organic material layer, an inorganic material layer, an organic material/inorganic material layer, an inorganic material/organic material layer, an inorganic material/organic material/inorganic material layer, or an organic material/inorganic material/organic material layer.
  • the organic material may be a PEO-based polymer, a siloxane-based polymer, a phosphazine-based polymer or a mixture thereof.
  • the inorganic material used for pretreating the lithium metal or included in the protective layer may be a lithium nitride, a lithium carbonate, a lithium silicate, a lithium borate, a lithium aluminate, a lithium phosphate, a lithium phosphorous oxynitride, a lithium silicosulfide, a lithium germanosulfide, a lithium lanthanum oxide, a lithium titanium oxide, a lithium borosulfide, a lithium aluminosulfide, a lithium phosphosulfide, or a mixture thereof.
  • the protective layer may have a high ionic conductivity for lithium ions.
  • a compound with very low ionic conductivity such as a lithium carbonate
  • a pretreatment layer since, as charging and discharging cycles repeat, a layer composed of a lithium carbonate cracks uniformly, thus allowing lithium ion conduction.
  • the pretreatment layer may be several nanometers to 1 ⁇ m thick, and may be in the range of tens of nanometers to 0.5 ⁇ m thick. If the thickness is less than several nanometers, the pretreatment layer's effect is minimal because it does not fully cover the lithium metal surface. If the thickness is greater than 1 ⁇ m, the energy density is adversely affected.
  • An organic layer may be coated as a protective layer using a coating method, such as knife coating, direct coating, reverse roll coating, gravure roll coating, gap coating, spray coating, slot die coating, or evaporation.
  • Gravure coating and slot die coating are advantageous, since they may provide a thin organic layer.
  • the organic layer may be about 0.1 to 10 ⁇ m thick. If the organic layer is less than 0.1 ⁇ m thick, a portion of the surface may not be coated. If greater than 10 ⁇ m thick, an undesirable overcharge may exist due to increased internal resistance.
  • the polymeric solution used for coating the organic layer may include fine polymer particles dispersed or fully dissolved. The latter case is advantageous because it may form a denser layer.
  • a solvent used in the polymeric solution may have a low boiling point for easy removal, and it should not form a residue.
  • the solvent may be the same solvent used in the electrolytic solution. Examples include dioxolane, dimethoxyethane, acetonitrile, dimethyl carbonate, tetrahydrofuran, and other similar substances.
  • the organic layer may have the general characteristics of polymeric electrolytes, such as electrochemical stability, ionic conductivity, resistance to a solvent (i.e., insolubility in electrolytic solution), and other similar characteristics.
  • the organic layer may be cured to enhance its mechanical properties and its resistance to a solvent. Types of curing include heat curing, UV light curing and curing by electron beams.
  • the substrate that includes the release component includes the release agent formed on the polymeric film or metallic film.
  • the release agent may be a silicon-containing compound, polyolefin, polyfluorocarbon, polyamide, polyester, polycarbonate, polyurethane, polystyrene, polycaprolactone, and mixtures and copolymers thereof. More preferably, it is a silicon-containing compound having the following formula:
  • R 1 to R 4 are independently a C 1-7 alkyl group, a C 1-7 heteroalkyl group, a C 6-20 aryl group, a C 7-30 arylalkyl group, a C 4-30 heteroaryl group, or a C 5-30 het
  • the substituents R 1 to R 4 should not all be aliphatic compounds having more than 7 carbon atoms since it is difficult to prepare or commercially obtain such a compound. Also, if the substituents R 1 to R 4 are all aromatic compounds having more than 20 carbon atoms in an aromatic ring, release agent flexibility undesirably deteriorates. Further, if n and m are greater than 1,000,000, the release agent's release property is low.
  • a layer of the release agent may be about 0.1 to about 5.0 ⁇ m thick. If the release layer thickness is less than about 0.1 ⁇ m, its effect is too weak. If greater than about 5.0 ⁇ m thick, production costs are unnecessarily high.
  • the release layer may be formed by roll coating, spray coating, gravure coating, reverse gravure coating, Mayer bar coating, die coating or other similar means.
  • a commercially available substrate product that includes a polymeric film to which a release layer is attached may be used.
  • the substrate's lower portion may be a polymeric film composed of polyester, polyethylene, polypropylene or polyimide.
  • polyester include polyethylene terephthalate, polyethylene naphthalate and other like substances.
  • the lower portion of the substrate may also be a metallic film composed of Ni, Ti, Cu, Ag, Au, Pt, Fe, Co, Cr, W, Mo, Al, Mg, K, Na, Ca, Sr, Ba, Si, Ge, Sb, Pb, In or Zn.
  • the polymeric or metallic film may be about 2 to about 100 ⁇ m thick.
  • the lithium metal anode's current collector may be composed of Ni, Ti, Cu, Ag, Au, Pt, Fe, Co, Cr, W, Mo, Al, Mg, K, Na, Ca, Sr, Ba, Si, Ge, Sb, Pb, In or Zn.
  • the current collector may be about 100 ⁇ to about 5 ⁇ m thick. If the current collector is less than about 100 A thick, it becomes difficult to prepare or handle. If greater than about 5 ⁇ m thick, its energy density may be adversely affected.
  • the current collector may be a ready-made metallic foil attached to the substrate, or it may be deposited on the substrate by conventional deposition using heating. If formed by deposition, a deposition rate may be in the range of about 0.1 to about 1000 ⁇ /sec. If the deposition rate is less than about 0.1 ⁇ /sec, production efficiency may be decreased. If greater than about 1000 ⁇ /sec, the release property may deteriorate.
  • the deposited lithium metal may be about 1 to about 200 ⁇ m thick. If less than about 1 ⁇ m thick, the battery may have a low capacity. If greater than about 200 ⁇ m thick, the energy density may be adversely affected.
  • a separator may be attached to the pretreated lithium metal or the deposited protective layer.
  • the separator may prevent possible damage to the lithium metal anode when it is released from the substrate, and it protects against tension applied during a subsequent winding process.
  • the released lithium metal anode may have a current collector/lithium metal/protective layer/separator layere structure.
  • the separator may be attached to the protective layer after it dries. Alternatively, the separator may be attached to the protective layer immediately after the layer is coated on the lithium metal surface, and then the product can be dried. While the latter case has a longer drying time, it provides close adherence between the separator and the protective layer.
  • FIG. 1 is a cross-sectional view of a lithium metal anode after a separator 4 is attached and before being released from a substrate.
  • a current collector layer 1 , a lithium metal layer 2 , a protective layer 3 , and a separator 4 are sequentially disposed below a substrate including a polymeric or metallic film 6 formed on a release layer 5 .
  • a lithium metal anode prepared by the method of the present exemplary embodiment has a current collector containing Si or F on an exposed surface.
  • the F derives from a release agent containing an F component.
  • a silicon resin composition including 22.5% by weight Syl-off 7900, 2.5% by weight Syl-off 7922 and 75% by weight water was coated on a 25 ⁇ m thick polyethylene terephthalate film using the Mayer bar coating method. Next, the coated substrate was dried at 180° C. for two minutes to obtain a 0.3 ⁇ m thick silicon resin release layer. Copper was deposited on the release layer to a thickness of 3000 ⁇ at a deposition rate of 10 ⁇ /sec. Lithium metal was then deposited to a thickness of 15 ⁇ m on a surface of the deposited copper. Finally, the lithium metal anode was released from the polyethylene terephthalate substrate.
  • a lithium metal anode was prepared in the same manner as in Example 1, except that the copper deposition rate was 50 ⁇ /sec.

Next, the coated substrate was dried at 180° C. for two minutes to obtain a 0.3 ⁇ m thick silicon resin release layer. Copper was deposited to a thickness of 3000 ⁇ on the release layer at a deposition rate of 10 ⁇ /sec. Lithium metal was then deposited on a surface of the copper to a thickness of 15 ⁇ m.
  • a lithium metal anode was prepared in the same manner as in Example 6, except that after the formation of the organic protective layer, a 15 ⁇ m thick polyethylene separator was attached to it.
  • a 25 ⁇ m thick polyethylene terephthalate film was used as a substrate. Copper was deposited to a thickness of 3000 ⁇ on the polyethylene terephthalate film as a current collector at a deposition rate of 10 ⁇ /sec.
